TEMPORARY BINDER.

SPECIFICATION forming part f Letters Patent No. 579,17 5, dated March 23, 1897'.

Y Application filed .April 25, 1896. Serial No. 589.007. (No model.)

To ail whom, it may concern:

Be it known that I, CHARLES E. PARKER, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Temporary Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 1o the art to which it appertains to make and use the same. I

This invention relates to the class of inventions known as temporary binders.

The main objects in the present instance are to construct such a binder as to more cspecially adapt it for use in connection with the mercantile or express business, the same being applied to the ordinary delivery, invoice, receipt, or other book commonly em- 2o ployed, and which contains a number of leaves heldin place during use, and which are intended to be subsequently removed and iiled away for future reference; to so construct the binder as to adapt it to be readily and cheaply manufactured and applied to the books and when in position thereon to effectually retain said leaves in position and against any possible displacement during use, and Without any puncturing or other marring, 3o and yet be capable of permitting of an instantaneous and ready removal of them when desired and the insertion of others when occasion requires.

Other objects and advantages of the invention Will hereinafter appear and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective view of an ordinary form of de- 4o livery, receipt, or invoice book having my temporary binder applied thereto. Fig. 2 is a transverse sectional view of the two :meeting ends of the book thus shown. Fig. 3 is a sectional view similar to Fig.v 2, with the eX- ception that but one end of the book is shown and the temporary binder is illustrated as open for the introduction of a new supply of leaves or for a removal of such as have been used, the section being taken on the line 3 3 5o of Fig. 4.. Fig. e is a front elevation, the parts being in the same position as they are shown in Fig. 3. Fig. 5 is a detail in perspective of the locking-latch. A

Like numerals of reference indicate like parts in all the figures of the drawings.

The binder consists of two light metal leaves-to wit, a stationary or securing leaf l and a swinging or movable clamping-leaf 2 the same being of equal length and provided at their outer edges, at their ends, and cen- 6o ters with companion hinge-eyes 3 for the reception of a pintle l of a length corresponding to that of the leaves l and 2.

Encircling the pintle at each side of the central hinge eyes 3 and extending from 65 thence to the end hinge-eyes is a pair of coiled springs 5 and 6, one terminal of each of which overlaps the stationary or securing leaf l and the other terminals of which overlap the clamping-leaf 2, the tendency of said 7o springs being to normally close the clampingleaf upon the securing-leaf. The stationary or securing leaf being riveted or otherwise secured upon the free end of the book-cover section 7 it will be seen that a series of loose 75 leaves or pages 8, as are commonly employed in books of this kind, mayhave their ends caught and clamped by the leaf 2 upon the leaf l, and are thus held securely yet removably between the book-covers 7 and 9, and that when thus `8o held the book may be freely handled., as in ordinary use, and yet the leaves 8 .always maintained in place in a perfectly-accessible manner; furthermore, that by swinging the clamping-leaf of the binder outward against 8 5 the tension of the springs the leaves 8 may be removed unmarred and iiled laway for future reference. In orderto make this clamping and retaining action more sure and positive, I prefer to make the leaf 2 slightly 9o wider at each side of its'center than the leaf l and to bend such portions of its free edge inward, as at l0, thus producing clampingflanges.

Centrally pivoted at Il to the outer surface of the clamping-leaf 2 and adapted to vibrate thereon in a lateral direction is a latch l2. (Best shown in the'detail view in Fig. 5.) As therein illustrated, it will be seen the latch is provided with a shouldered lug roo 13 at one end that extends at a right angle thereto, said lug having that portion above its shoulder beveled, a central eye 1-1 for the reception of the pin 11, by which it is fulcrumed or pivoted, and an eye 15 at its Opposite end, the latter eye 15 being disposed at a right angle to the disposition of the eye 14. This eye 15 is for loosely receiving the pintle 4 at one side of the central hin ge-eye 3 of the fixed or securing leaf 1 and is located between the same and the end of the`neXt adjacent coiled spring G, said spring bearing` against the latch and forcing the inner end of the same upwardly against the shank or shoulder 16, formed immediately below the central hinge-eye 3.

At one side of the eye 15 a notch 17 is formed, and leading to the notch and curved concentrically with the eye 15 there is produced an inclined shoulder 18, the same extending from a point near the latch, but stopping short of the same and producing a second notch 19.

W'hen the leaves 1 and 2 are closed upon the loose leaves S andthe book-covers likewise closed, the shouldered catch-lug 13 passes through an opening 20, formed in the bookcover 9 and in a metal plate 21, applied to the outer surface of said book-cover, with the edge of which said shoulder is thrown into engagement by the influence of the spring 6, and thus the book is retained closed. The book, however, may be readily opened by pressing the latch laterally through the medium of the lug 13 against the tension of its spring 6. By swinging the leaves of the book closed the edge of the plate 21 is caused to ride over the inclined face of the lug 13 of the latch, the edge of the plate being engaged by the shoulder of said latch, so that the book is maintained closed. The opening and closinggof the book, it will be seen, in no wise disturbs or releases the loose leaves S, as the latter are held firmly in position by the swinging leaf 2, that is influenced by the coil-springs, as before described.

Vheu the clamping-leaf 2 is closed or in its clamping position upon the loose leaves 8, the notch 19 of the latch 12 engages with the shank 16 below the central hinge-eye 3, that is formed on the edge of the stationary leaf 1. To open the clamping-leaf 2 in order to release the loose leaves S, it is simply necessary to laterally vibrate the latch 12, so as to disengage its notch 19 with the shank or shoulder 16 and subsequently swing the clamping-leaf at a right angle to the leaf 1. In doing so the inclined shoulder 1S rides against the shank or shoulder 1G, compressing the spring G until the notch 17 of the latch comes opposite the shank or shoulder 16, when the latch is caused to vibrate in an opposite direction and the notch 1.7 becomes engaged with the shank or shoulder 1G, so that the parts become locked against the tension of the springs 5 and G and the clamping-leaf is held open while the loose leaves 8 are removed and a new lot substituted. By a vibration of the latch against the tension of its spring G the notch 17 is disconnected from the shank or shoulder 10, and the springs 5 and 6 quickly snap the clamp upon the paper.

From the foregoing description, in connection with the accompanying drawings, it will be observed that I effectually accomplish all the objects of my invention as set forth hereinbefore and have produced a simple temporary binder that may be applied to the back section of any book cover or other base, and which when in position will securely maintain a series of leaves such as are commonly employed in position for writing, and which will release the same, and furthermore accomplish this without any marring whatever. lt will further be observed that the latch not only secures the backs of the book together, so that the book maybe thrown around and carelessly handled without disturbing its contents, but the latch further serves the purpose of locking the clampinglcaf of the binder open,whereby the old leaves may be removed and new ones substituted.

l do not limit my invention to the precise details of construction herein shown and described, but Ahold that I may vary the same in regard to such details within the knowledge of the skilled mechanic without departing from the principle of my invention or sacriflcing any of its advantages.

Having described my invention, what I claim is- 1. The combination with a book-cover or other base, of a pair of metal leaves hinged together at their outer edges, and one of said leaves being secured to one edge of one of the cover-sections or base, of a spring for norm ally closing the remaining leaf, and a springoperated latch for locking said remaining leaf in an open or separated position against the tension of the said spring, substantially as specified.

2. The combination with book-cover sections, of a pair of metal leaves, the inner one of which is secured to one of the sections of the cover, hinge-eyes arranged at the outer edges of the leaves, a pintle connecting the eyes, a coiled spring arranged upon the pintle and having its terminals embracing the outer sides of said leaves, a latch pivoted on the outer or movable leaf and at its outer end having an eye loosely receiving the pintle and borne upon and influenced bythe spring, said latch being provided at one side of its eye with a notch for engaging the opposite or xed leaf whereby the leaves may be maintained separated against the tension of the spring, substantially as specified.

3. The combination with book-cover sections, of a met-al leaf secured to one edge of one of the same, a clamping-leaf hinged thereto, a spring for normally closing the clampingleaf upon the secured leaf, a latch pivoted on the clamping-leaf and provided with a shank or shoulder extended at an angle thereto, and an opening arranged in the opposite portion IOO IIO

of the cover for the passage therethrough of said lug and designed at one edge to engage with theshoulder of the same, substantially as specied.

4. The combination with book-cover sections, of a fixed metal leaf applied to one edge of one of the same and provided with central and end hinge-eyes, a clainping-leaf having companion hinge-eyes, connecting-pintle, springs interposed between the hinge-eyes and arranged upon the pintle and having their terminals embracing the said leaves, the latch 12 pivoted on the clamping-leaf and at its rear end having the eye 15,notches 17 and 19 and intermediate inclined shoulder 1S, all arranged as shown, said eye receiving the pintle and being borne upon by the end of the spring, the beveled shouldered lug 13 at the opposite end of the latch, and the opening 20 in the opposite side of the book-cover for receiving the lug, substantially as specified.

5. The combination with book-cover sections, of a pair of hinged leaves, the inner one of which is secured to one edge of one of said sections, a spring for normally closing said leaves so as to clamp a series of loose sheets or leaves of paper, and means actuated by said spring for locking the book-cover closed and for retaining said hinged leaves in an open or separated position against the tension of their spring, substantially as specified.

6. The combination With book-cover sections, olfa pair of hinged clamping-leaves, the inner one of whichv is secured to the edge of one of said sections, a spring for normally closing the leaves, whereby the same are adapted to secure a series of loose sheets of paper, and a latch pivoted on the outer movable leaf and actuated by said spring to engage and lock With the stationary leaf when the saine are opened and to engage and secure the book-cover when the same is closed, substantially as specied.

In testimony whereof I affix my signature in presence of tWo Witnesses.
